The Validity Of The Nexus 3D Cube Test
Now I know the golden rule when it comes to trolls is to ignore them but most people will know by now that if someone comes at me with a load of bollocks then it gives me the right to reply. I've made it very clear how I feel when it comes to testing metal detectors above ground. In my mind it can show potential performance, the ground and dirt is a complicated aspect and when it comes into play, things change. I've stated that most of my machines perform better in the ground than in air, I've also said that I believe digital machines perform better in the air than in the ground.

| What's The Validity Of Any Above Ground Tests? |
Let me use my Equinox 800 as an example, in air tests it displays incredible depth on coins, way over a foot on a cartwheel penny but there's no way on earth that it will hit that same coin in the ground at that depth. In my fields my Equinox 800 pretty much maxed out at the length of a pin-pointer. In regards to unmasking, when targets, both ferrous and non-ferrous have been in the ground for decades they become impregnated into the soil and roots, there are no air pockets and you also get leakage. I believe these elements change a machines ability to unmask, for machines that perform better in the ground I believe these elements aid its ability. People might disagree with this but from decades of metal detecting these are the conclusions I've arrived at.
There Is No Validity To The Nexus 3D Cube Test?
A few people have contacted me stating that there is no validity to the Nexus 3D cube test, fair play, but there is actually no validity to any above ground test. There's no validity in swinging a coil on concrete over iron and coins stuck to wood, there's no real evidence that a machines ability to unmask in a raised nail test actually aids the performance of that specific machine when hunting for targets in the ground. We will never be able to reproduce 'in ground' conditions above the ground, that really is just common sense.
What the Nexus 3D cube does allow is a chance for everyone anywhere in the world to use the same set of materials to measure a machines potential unmasking performance, that's pretty much it. Results shouldn't be taken as gospel, maybe this should be looked upon as a bit of fun instead of a reason to wage war on individuals and the brand of machines they choose to use. In the two videos that I've uploaded the Nokta Legend hasn't performed as well as my Nexus Standard MP V3 or Laser B3 Power Max. I can't help but think that if the results were the other way around, a certain type of person out there wouldn't be questioning the "validity" of the test.
Physics class. Any energy hitting an singular atom that is not in a lattice will radiate that energy away directly. Air is a loosly packed lattice so the energy doesn't scatter or get absorbed easily. But a coin at depth is covered with a lot of atoms, they are not packed dense enough or under pressure so the atoms in the coin will not absorbed the energy radiated from the coil. However a lot of scattering is going on and less energy gets back the secondary coil.
ReplyDeleteThe reason why you can "see" the coin that is directly under the iron bar or disc is because the energy passes trough the iron in both directions. Since the non ferrous object has heavier atoms it will radiate more and therfore gets picked up by the machine. The more energy youbeam down the more you can pick up. Due to health hazard detectors are limited to something like one watt by law. This means that all current machine radiate the same amount of energy, but the more processing you do with incomming energy means you will loose signal reception power.
So, you boost the radiation by dragging a car battery and an amplfier along and you can detect really deep targets. But trust me after two digs, you go home exhausted. Jens Olsson aka mossig
Will you please show a demonstration with your original cutlass and the cube?
